StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 22 April 2026; the live site may have changed since.

xreso scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: no email security records.

Launched on Product Hunt on April 22, 2026. The site is hosted on Vercel, with a domain registered 4 days before launch. We've detected 15 technologies on this site, covering productivity, storage, video, and advertising. The stack includes Auth.js, Next.js, and React.

It's on one of the most common stacks we track, shared by 2,296 launches and more locked down than the typical Product Hunt launch.
